Title: Receiver group selection minimising the geometric dilution of precision
Inventor: THOMAS DAVID WYNNE
IPC: G01S5/02
Filed: 2006-12-01
Abstract: A number of receivers are provided for determining the location of a target or aircraft via multilateration. Groups of receivers to be used are selected to give the best Geometric Dilution of Precision GDOP result by eliminating the receiver that has the greatest group time delay contribution. In this way the group to be used may be selected as appropriate for the location of the target in real time avoiding the requirement to have a database holding the groupings to be used.

Title: A stabilising and release system for and boom holding and positioning system for an agricultural apparatus
Inventor: MURPHY RICHARD
IPC: A01D34/66
Filed: 2007-02-21
Abstract: A stabilising and release system, for an agricultural apparatus (1) having a mounting portion (2) for mounting the apparatus (1) to a tractor, a pendulum (10) mounted on the mounting portion (2), and a boom (26) for spraying or cutting, which is pivotally mounted to the pendulum (10) at a pivot point so as to allow pivoting of the boom (26) relative to the pendulum (10). The system stabilises the boom (26) against movement imparted to it by disruptive forces which disturb the natural position of the boom (26) by proving a rigid damper (60) arranged between the support frame and the boom (26) and arranged to damp relative movement of the boom (26) and the mounting frame caused by said disruptive forces, the damper (60) has an articulated coupling (61, 62) which allows the damper (60) to articulate so that the damper (60) can follow the motion of the boom (26) thus damping any undesired swaying action caused by bumps and ruts over which the tractor passes.

Title: Method for controlling direct injection of a gaseous fuel at a variable supply pressure
Inventor: BOYER BRAD ALAN
IPC: F02D19/02
Filed: 2007-09-11
Abstract: A method for controlling direct injection of a gaseous fuel in an internal combustion engine 10 by adjusting injection time or injection duration based on a variable supply pressure, which may decrease as fuel tank pressure decreases; and possibly also on an in-cylinder pressure sensor. Spark timing and throttling may be controlled based on information from an exhaust oxygen sensor 38. Injection may start near the end, e.g. near top dead centre, of a compression stroke. Pressure supplied to the injector 30 may be regulated by a pressure regulation device, possibly including a variable pressure regulator. The injector 30 may be piezoelectric or magnetostrictive. A second fuel tank may be selectively connected to the first tank through a controllable check valve in order to regulate the pressure of the fuel delivered to the injector 30 as the pressure in the first tank and the engine condition vary.

Title: Method and system for determining traffic congestion.
Inventor: SATOH TAICHI
IPC: G08G1/01
Filed: 2007-12-21
Abstract: A system for determining traffic information comprises a map acquiring unit and a traffic information acquiring unit. The map unit is configured to acquire map information which includes speed limit data for a plurality or road links. The traffic unit acquires traffic messages from a traffic information centre about the congestion state of a road section and may also include an average speed for the congested section. In use, a determination of traffic congestion uses the congestion rating from the centre if the average speed is not included in the message (S50, S90). If an average speed is included and no speed limit data is found then the average speed is used to determine the degree of congestion (S60, S80). If the average speed information and speed limit information are both present then the determination is based on both values (S70). The device may include a storage means for storing a correspondence between average speeds and traffic congestion for road links (Fig 3b). Further apparatus may include a means for notifying the use of the degree of congestion for the road section (S100).

Title: Verification of accelerometer operation by channelling high frequency signal across leads
Inventor: MERWE GERT J VAN DER
IPC: G01M15/02
Filed: 2008-12-10
Abstract: The operation of an accelerometer 100 is tested by channelling 302 a high frequency (HF) signal through a positive lead 104 and detecting 304 a signal at a negative lead 106 thereof. The integrity of the accelerometer is verified 308 if the detected signal is substantially similar to the high frequency signal. Preferably, the HF signal is channelled through a piezo element 108 of the accelerometer. Preferably, intermittent faults can be distinguished 310 from continuous faults. The HF signal may be channelled continuously, may be channelled prior to operating a machine being monitored by the accelerometer and may have a frequency that is different from an operating frequency of that machine. The HF signal is generated from a charge converter comprising an appropriate signal source and the arrangement is used to monitor rotor unbalance in a turbine engine.

Title: Methods of protecting security documents from counterfeiting
Inventor: SWIFT PATRICK
IPC: G06K9/74
Filed: 2007-11-14
Abstract: A method of protecting a security document from counterfeiting includes applying at least one security element containing a concealed Fourier pattern to the document. The concealed Fourier pattern is produced from a master Fourier profile, and is applied to the document by embossing, engraving, laser ablation or chemical etching, and/or by a cylinder or plate bearing the master Fourier profile. When a counterfeit security document produced without knowledge of the master Fourier profile is scanned or imaged and subjected to a Fourier transform, the resulting test Fourier pattern will differ from a master Fourier pattern corresponding to the master Fourier profile for the authentic security document. In a particularly preferred embodiment, the concealed Fourier pattern is applied to the document by rotogravure printing.

Title: Electrode clamp
IPC: H05B7/105
Filed: 1957-03-27
Abstract: 809,986. Furnace electrode holders. SUNROD MANUFACTURING CORPORATION. March 27, 1957 [April 13, 1956], No. 10062/57. Class 39(3) A furnace electrode clamp comprises a plurality of arcuate conductor shoes having wedge 'faces co-operating with wedge members which are interconnected in groups of at least two so that any wedge member moving with a wedge face transmits opposite movement to another wedge member or members. As shown, an electrode clamp comprises six arcuate contact shoes 1 each supported by two electrical conductors 5 from a bus ring 6 consisting of two tubular rings 7 and 8 joined by clamps 9, a water cooled mantle 4 with a lower reinforced annular portion 12 and upper and lower sections 4a and 4b hung from a suspension ring 10 which is supported by three straps 84, and six wedge members W. A hydraulic cylinder 59 with its associated linkage mechanism connected between the suspension ring 10 and the bus ring 6 provides power to move the latter vertically so that the shoes 1 may be forced against the electrode E by the wedging action of the members W. Each shoe has three wedge faces 20 which cooperate with the inner sloping surfaces of three wedges 22 which are arranged on a supporting plate P to form the wedge member W, the outer vertical faces of which co-operate with the reinforced portion 12 of the mantle surface. Rollers or balls are located between the surfaces to decrease friction. Adjacent wedge members are arranged in pairs, and are connected to pivoted levers (Fig. 5, not shown) on the suspension ring 10 by supports 30a and 30b so that the movement of one member transmits opposite movement to the other member, thus equalizing the pressure should one shoe come up against an irregularity on the electrode surface. The shoes 1, the conductors 5, and the bus ring 6 are insulated from the rest of the clamp. Nine contact shoes (Fig. 6, not shown) or twelve contact shoes (Fig. 7, not shown) may be used. The wedge surface slope may be in the opposite direction to that shown, the clamping action then being effected by raising the bus ring and shoes; or the clamp may be supported from the bus ring 6 and the clamping action effected by forcing the suspension ring 10 upwardly,
